The emergency response procedures for the Fusion Hybrid, MKZ Hybrid and Fusion
Energi vehicles are similar to those for traditional gasoline-powered vehicles with the
addition of special considerations for the high-voltage electric system components.
The Fusion Hybrid, MKZ Hybrid and Fusion Energi vehicles use a conventional gasoline
engine in addition to an electric motor to power the vehicle.
• Gasoline is stored in a traditional fuel tank.
• Electricity is stored in a high-voltage battery pack.
The combination of a gasoline engine and electric motor provides for improved
performance (V6 performance with a 4-cylinder engine and electric motor), reduced
emissions and improved fuel economy . The Fusion Hybrid and MKZ Hybrid high-voltage
systems are self contained, never needing to be plugged into an electrical outlet for
recharging. The Fusion Energi high-voltage system can be plugged into an electric outlet
for recharging to optimize the vehicle’s extended electrical range. Both vehicle systems
incorporate a generator that charges the high-voltage battery during cruising and braking.
The information in this guide will allow response to emergencies involving the Fusion
Hybrid, MKZ Hybrid and Fusion Energi vehicles to be as safe as non-hybrid vehicles.
The Fusion Hybrid, MKZ Hybrid and Fusion Energi vehicles have been designed with
many safety features for your protection. These features help provide safe access to the
vehicle under various conditions; however, when approaching a high-volt age vehicle in a
fire, rescue or recovery situation, always follow one industry standard rule:
• The Fusion Hybrid and MKZ Hybrid vehicles can easily be identified by the
“Hybrid” badges located on the left and right front doors. There is a “Hybrid”
nameplate on the trunk lid (located on the right hand side) that also includes
the green leaf/blue highway “Hybrid” icon.
NOTE: Fusion Hybrid shown, MKZ Hybrid similar.
• The Fusion Energi vehicles can easily be identified by the “Energi” badges
located on the left and right front doors. There is a “Energi” nameplate on the
trunk lid (located on the left hand side) that also includes the green leaf/blue
highway “Hybrid” icon.
NOTE: Fusion Energi shown.

The following list describes certain features that have been incorporated into the Fusion
Hybrid, MKZ Hybrid and Fusion Energi vehicles that allow for either simple or automatic
shut off of the high-voltage electrical systems.
• High-Volt age Fuse — In the event of a high-voltage short circuit, the high voltage fuse will open, disabling the high-voltage system.
• High-Voltage Interlock Circuit — Whenever a high-volt age connector
is disconnected, the high-voltage interlock circuit opens and disables
the high-voltage system.
• Ignition Key/Button in the OFF Position — Any time the ignition is in
the OFF position, the high-voltage system is disabled.
NOTE: If the vehicle is equipped with remote start, high-voltage may be
present in the system if the ignition is off.
NOTE: ENERGI vehicles, when plugged in for charging may have high-
voltage present in the system if the ignition is off.
• High-Volt age Service Disconnect — Whenever the high-voltage
service disconnect (located behind the rear seat back) is removed, the
high-voltage system is disabled. For additional information, refer to
Page 1 1 in this manual.
• Thermal Sensors — In the event the battery is exposed to extreme hot
ambient conditions and/or is being driven extremely aggressively with
compromised cooling, power limits will be employed to prevent overheating.
However, if the battery is in use and does become too hot, cont actors will
be opened and the vehicle will shut down. In some instances, if the ignition key
is left in the “ON” position, this could cause the high-voltage battery
temperature to exceed 60°C (140°F); if this temperature is reached, the
thermal sensors located near the high-voltage battery will automatically
disable the high-voltage battery .
